UNIVERSAL HAND-OPERATED MACHINE TOOL.

Application led Hay 4, 1916.

To all whom t may concern:

Be it known that I, MATHIEU LiNo'r'rE, a citizen of the French Republic, residing at Paris, France, have invented certain new and useful Improvements in Universal Hand-Operated Machine Tools, of which the following is a specification.

This invention relates to a universal hand operated machine tool, that is to say one by which various operations such as drilling, grinding, sawing, and the like can be efiiciently carried out.

The machine tool according to the invention is characterized in that the driving mechanism for rotating the various tools participates in the rising and falling movements of the tools.

One form of machine tool according to the invention is illustrated by way of example in the accompanying drawings in which Figure l is a front elevation.

Figure 2 is a side elevation, partly in section.

Upon a base plate a, which may be fixed on a bench in any suitable manner, is mounted a column b, upon which the body 0 may be fixed in any position whatever by means of a set screw c or otherwise. This body, cylindrical at its lower part, comprises, at its middle part, two cheeks c2, between which is mounted upon a shaft d, a sector or toothed pinion d operated by a lever d2, situated outside the body c. The upper cylindrical part c3 of the body is hollow a-nd surrounds a tube e, carrying at its upper part a shaft e on which is mounted a sprocket pinion e2. The tube e on one side is cut with rack teeth e3, meshing with the toothed pinion d', and is slotted at e4, e5, on the opposite side to the rack. Screws e6, e?, pass through 'the cylindrical part e3 and 4engage within these slots, guiding the tube e, within the cylinder e3. The lower screw e7 is extended into the interior of the tube e and forms an abutment for a coiled spring f, maintained at its upper part by a pin f. A piece g is fixed to the body, by the intermediary of a nipple g', held inside the hollow cylindrical part c3, of the body by a headless screw g2, or in any other suitable manner. The piece g, supports a shaft 71., carrying a grinding wheel t, a circular saw 7b2, a small sprocket pinion h3 and a bevel pinion JL. `The piece g, supports a Specification of Letters Patent.

second removable piece z', fixed in any desired manner, for example by means of two pins i', engaging within suitable holes in the piece g, and held by screws 2. The piece z', supports a vertical shaft 7c, upon which is keyed a1 bevel pinion 7c', engaging with the bevel pinion 7L". A chuck k2, is mounted on the shaft k and in which is fixed the tool to be used, for example the drill 7e3, countersink or the like. A crank Z, extensible in order to permit of increased leverage, is keyed on the shaft e', the crank imparting, by a chain Z, passing over the sprocket pinions e2 and h3, a rotary movement to the horizontal shaft it, that is to the grinding wheel L, the saw 7b2, and the drill or countersink 7c3 by the intermediary of the bevel pinions It and L, All the driving gear for the rotary movement is thus self-contained with the vertical tube e. A descending movement is given `to the tube, and all the members carried upon it, by means of a lever d2, operating the rack c3, by the pinion or toothed sector d', in such a. manner as to bring the different tools into contact with the pieces of work carried by the vice, at the same time that the rotary movement of the tools is effected by the crank Z.

When the operator releases the controlling lever d2 the coiled spring f, automatically returns the tube e, upwards, in such a manner as to leave the pieces of work free. A vice m, slidesl in the base plate t so that it can be removed therefrom. It has a stationary jaw m2 and a movable jaw ma, which is moved by a screw m4 carried by a lug m5 which is drilled and screw threaded to receive it. The vice can thus be withdrawn from the base plate a, of the machine, with a. piece of work still gripped in it between the jaws m2, m3, and similarly a piece of work can be placed in and gripped by the vice before the vice is placed in position on the base plate a. It is secured in position by a set screw m. In order to facilitate centering of the piece of work in the vice, each of the jaws of the latter has two axial V grooves n, n', at right angles to each other.

The body of the machine tool may be raised, lowered and set in any desired position, the set screw c enabling the body c to be iixed on the column in any desired position, the machine consequently permitting Working on pieces of Widely varying dimensions and at different angles. The machine tool may be used for drilling, grinding, sawing, or equally for turning, mortising, countersinking or the like. By removing the body of the machine the vice is rendered available for holding Work to be iiled or otherwise Worked upon by hand tools.

I claim l. A hand opera-ted universal machine tool comprising a plurality of shafts, tools on said shafts, driving mechanism for rotating said shafts, a tubular carrier for said shafts and driving mechanism, a base plate having a column fixed thereon, a body slidable and rotatable on said column, means for fixing said body in adjusted position on said column, rac-k teeth on said tubular carrier, a pinion on said body and meshing with said rack teeth, means for rotating said pinion, and a coiled spring Within said tubular carrier Vand having an abutment on said body for rais-ing said carrier relatively to said body, substantially as and for the purposes he'reinbefore set forth.

2. A hand operated universal machine tool comprising a carrier having a plurality of shafts fitted with tools, a base plate having a column fixed thereon, a body adjustably mounted on said column, means, carried by the said carrier, for rotating said shafts, means for raising and lowering said carrier relatively to said body, and a removable viceon said base plate, said vice having jaws the opposing faces of which each have tivo V grooves arranged at right angles to cach otherfor thepu-rpose hereinbefo-re set1 forth.

3. A hand operated universal machine tool comprising a vertical tubular carrier, tivo shafts, one vertical and the other horizontal, carried by the lower end of said tubular carrier, a horizontal shaft, having a sprocket pinion and a hand crank, mounted on the upper end of said tubular carrier, a sprocket pinion on the horizontal shaft carried on the lower end of said tubular carrier, a chain connecting said sprocket pinions, a base plate having a vertical column fixed thereon, a bodyT rotatable and slidable vertically on Vsaid column, rack and pinion mechanism for -loiveringsaid tubular carrier relatively to said body, and a spring for automatically raising said carrier relatively to said body, substantially as and for the punpo'se hereinbefore set forth.

In testimony 'whereof I have signed my naine to this specification in the presence of tivo subscribing Witnesses.
